Withdrawal from heavy barbiturate or alcohol use after a very long period of use has a high risk of death

Withdrawal from alcohol or barbiturates should not be sudden and without doctor's supervision, otherwise it can be fatal. The person can suffer from mild to severe withdrawal symptoms such as tremors, nausea, fever, severe diarrhea, etc. When the withdrawal is done under a doctor's supervision, they give relevant medicines to reduce withdrawal symptoms and thus calculate all risks.
